The New York Public Library. 151,000 square Ieet ol 
Monel .025" in thickness were used for a batten-type roof, 
eaves, gutters, and leaders. The Monel roof was installed 
in 1936- and replaced another metal with which the build-

of the building in 1936. 




Brooklyn Museum ol Arts and Sciences. Approximately 
12.000 square Ieet of .021 Monel sheet were used for 
standing seam roof, skylight and ventilators on wing D.

— Basic Data 









SIZES AND WEIGHTS 

Monel Roofing sheet is furnished in a wide variety of sizes 
and gauges. Standard dimensions of sheets most commonly 
employed for roofing are 24" x 96", 30" x 96", 36" x 96". Gauges 
recommended for roofing work are No. 24 and No. 25 U. S. 
Standard, .025" and .021" respectively. These are comparable 
in weight and thickness with 20 oz. and 16 oz, copper. Weights 
per square of Monel Roofing are given in Table II. 

APPLICATION 

Monel Roofing is adapted to installation with batten seam, 
standing seam or fiat seam. Its use imposes no special struc- 
tural requirements beyond those generally followed for any 
high grade sheet metal roofing. Roof decks may be of wood, 
cement, steel, gypsum or rigid insulation. They should be 
rmooth and free from ridges or depression, clean and thoroughly 
dry he fore the roofing is applied. The customary layer of roof- 
ing felt should be installed under all Monel roofs. Limitations 
of pitch for the various types of roofing are standard, namely: 
4" per foot minimum for batten roofings, 2" per foot minimum 
for standing seam, and about V per foot for flat seam. 

INSTALLATION 

No special technique is required for installing Monel Roof- 
ing. The following general rules should be observed: 

1. Bends and seams should be made with a radius at least 
equal to twice the thickness of the sheet. 

2. Vse Monel clips, cleats and nails for attachment; do not 
nail through sheets. 

3. Where soldering is necessary, joints between sheets should 
be locked and the solder thoroughly sweated into the joint. 

4. Monel sheets are soldered by the same procedure as that 
used on copper; pre-tin edges of sheets with soft solder before 
soldering and use a killed acid flux with a small amount of 
ammonium chloride. High or low tin solders are equally ef- 
fective. 

5. Expansion joints and locked seams should be installed in 
accordance with standard roofing practice to allow for a free 
movement of .186" in a 10-foot length through a 200F tem- 
perature change. Otherwise the roofing may break at the 
seams under expansion and contraction of the sheets which 
are rigid and resist buckling. 

COST 

The cost of Monel Roofing installed is greater than that of 
other commonly used metals. Comparative estimates for new 
work and records of replacement installations show that the 
cost of Monel Roofing installed, including contractor's labor, 
overhead and profit, will range from 12%$ to 25Cc more than 




Installation of Monel Roofing follows practice recognized as standard 
for other types of sheet metal roofing. Left, applying Monel Roofing 
with Monel clips and nails; center, soldering a gutter expansion joint; 
right, bolting a ventilator cowl. Monel Roofing can be installed with 
flat seams (Rg. A) standing seams, (Fig. B) or batten seams (Fig. C)

However, experience with Monel roofs has indicated that ex- 
pense for maintenance is negligible. Costs of Monel Roofing 
figured over a period of years on a comparative basis should, 
therefore, be actually lower than those of less durable materials 

TECHNICAL SERVICE 

The International Nickel Company does not attempt to under- 
take the function of architect or contractor in roof design or in 
the installation of sheet metal roofing. Through its Technical 
Service Division, however, architects and contractors can free- 
ly obtain data on problems involving the use of Monti Metal, 
assistance in the solving of any unusual problems and any sup- 
plementary information regarding Monel products that may 
be desired. 

WHERE TO BUY 

Monel Roofing is furnished and installed by roofing con 
tractors thoroughout the country Additional information and 
assistance in developing estimates will gladly be given by The

GOOD REASONS 

FOR USING ^©^ 



t 



It resists the highly corrosive atmospheres of 
urban areas, containing fumes, smoke, and 
soot. Monel cannot rust. 



C This metal has a lower coefficient of thermal 
expansion and contraction than other high 
grade roofing metals, and therefore withstands 
the effect of temperature changes better. 



O Monel is strong— Monel's strength plus corro- 
sion resistance provides a higher factor of 
safety than other metal roofing sheets. 



G. Monel is highly resistant to fatigue under re- 
peated flexing, thereby preventing "wiggle" 
cracks and weather cracking. 



O This metal is rigid— its modulus of elasticity is 
26.000,000 psi. This greater stiffness makes 
Monel highly acceptable for self-supporting por- 
tions of roofs, such as cornices and gutters. 



*7 Monel roofs may be grounded to provide ade- 
quate protection against lightning. 



8. 



Weathered Monel is neutral in color and does 
not detract from other architectural features. 



A Monel is harder and tougher than other com- 
mercial roofing materials. It resists wear from 
sliding snow, the scuffing of feet, and erosion by 
rain water. 



O Monel, while tough and hard, is readily fab- 
ricated—irregular roofing contours, decorative 
designs, skylight frames, ventilators, downspouts, 
gutters, and miscellaneous metal work present no 
difficulties when using Monel. 



WHERE MONEL ROOFS ARE USED 

Monel roofs are well suited to monumental buildings — railroad stations, hospitals, schools, 
libraries, churches, museums, office buildings, etc. While higher in initial cost, its durability and 
freedom from maintenance expense makes its use most economical over a long period of years. 

MONEL ACCESSORIES 

It is advisable to install Monel fittings and hardware on a Monel roof for an "all Monel" job. 
Monel nails, cleats, screws, bolts, etc., are readily available. Monel accessories are also useful 
for making repair jobs on roofs made of other materials. Write for Bulletin H-2, "Monel Metal 
Accessories."
